이뿐만 아니라 투피스 타입 임플란트(A)는 픽스쳐(10)에 어버트먼트 삽입홈(11)을 형성시킨 후 어버트먼트(20)를 어버트먼트 삽입홈(11)에 끼우도록 하는 구조이므로 어버트먼트 삽입홈(11)을 통해 이물질이 픽스쳐(10) 내부로 유입되어 악취가 발생하고 치주염 발생의 원인이 된다는 단점이 있었다.In addition to this, since the two-piece type implant (A) has a structure in which the abutment insertion groove 11 is formed in the fixture 10 and then the abutment 20 is inserted into the abutment insertion groove 11, the abutment There was a disadvantage that foreign substances were introduced into the fixture 10 through the ment insertion groove 11, causing a bad odor and causing periodontitis.
한편, 원피스 타입 임플란트(B)는 픽스쳐(10)와 어버트먼트(20)가 일체를 이루고 있는 것인데, 치조골에 시술후 어버트먼트(20) 부위가 환자의 잇몸으로부터 7mm 이상 돌출되어 있기 때문에 환자의 혀 또는 음식물 섭취중에 돌출부(120)에 충격이 쉽게 작용되어 미세한 동요에 의해 임플란트의 초기고정 시간이 지연되고 초기고정에 실패하는 원인이 되기도 하는 문제점이 있었다.On the other hand, the one-piece type implant (B) is one in which the fixture 10 and the abutment 20 are integrally formed. There is a problem that the initial fixation time of the implant is delayed due to minute fluctuations because the impact is easily applied to the protrusion 120 during the ingestion of the tongue or food, and it is also a cause of failure of the initial fixation.
그리고 원피스 타입 임플란트(B)는 어버트먼트(20) 부위가 픽스쳐(10)와 일체를 이루고 있으므로 어버트먼트(20)가 수직 상방으로 길게 돌출되는 형태로만 제공되고 있고, 이로 인해 임플란트 식립 후 인접 치아와의 PATH를 맞추기 위해서는 픽스쳐(10) 부위와 어버트먼트(20) 부위의 경계 부위에 기계적 힘을 가하여 소정의 각도로 구부리도록 하는 방식으로 인접 치아와의 PATH를 맞추었다. In addition, the one-piece type implant (B) is provided only in the form in which the abutment 20 is integrally formed with the fixture 10, so that the abutment 20 protrudes vertically upward, and for this reason, the abutment 20 is adjacent to the implant after implantation. In order to match the PATH with the teeth, the PATH with the adjacent teeth was matched by applying a mechanical force to the boundary between the fixture 10 and the abutment 20 to bend it at a predetermined angle.
원피스 타입의 임플란트(B)를 강제적으로 구부려 사용함에 따라 심미성이 부족하고 저작능력이 저하되는 원인이 되었으며, 강제적으로 구부린 부위에 피로가 쉽게 누적되어 파단되는 현상이 자주 발생되었다.As the one-piece type implant (B) was forcibly bent and used, it lacked esthetics and caused a decrease in masticatory ability, and fatigue easily accumulated in the forcibly bent area and fracture occurred frequently.
이에 본 발명에서는 원피스 타입 임플란트와 투피스 타입 임플란트의 장점은 확대하고 단점은 보완할 수 있는 하이브리드 임플란트를 제공하고자 한다.Therefore, in the present invention, it is intended to provide a hybrid implant that can expand the advantages of the one-piece type implant and the two-piece type implant and compensate for the disadvantages.

An object of the present invention is to provide a hybrid implant that can solve the problem of screw breakage that occurs frequently in type implants.
그리고 본 발명은 기존 투피스 타입 임플란트의 문제점 중 하나인 이물질 침투로 인한 악취 유발 및 치주염 발생의 원인이 원천적으로 발생되지 않도록 하는 하이브리드 임플란트를 제공하고자 한다.In addition, the present invention is to provide a hybrid implant that prevents the occurrence of odor and periodontitis caused by infiltration of foreign substances, which is one of the problems of the existing two-piece implant.

이하 첨부되는 도면을 참조하면서 본 발명에 대하여 보다 상세한 설명을 하기로 하며, 제시되는 도면들은 본 발명의 기술적 사상에 대한 실시 가능한 예를 보여주는 것이다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings, and the presented drawings show examples of possible implementations of the technical idea of the present invention.
도시된 바와 같이 본 발명에 따른 하이브리드 임플란트는 기존의 원피스 타입 임플란트와 투피스 타입 임플란트의 장점을 접목한 것이다.As shown, the hybrid implant according to the present invention combines the advantages of the existing one-piece type implant and the two-piece type implant.
픽스쳐(100)는 스크류(111)를 갖는 바디(110)와, 바디(110)의 상단면으로부터 소정각도로 돌출됨으로써 경사진 결합면(121)을 갖는 돌출부(120)를 포함한다.The fixture 100 includes a body 110 having a screw 111 and a protrusion 120 having a coupling surface 121 inclined by protruding at a predetermined angle from the top surface of the body 110 .
도 6처럼 픽스쳐(100)의 하단으로부터 소정 높이까지 외면에 스크류(111)가 형성되며, 스크류(111)는 치조골에 식립된다. 스크류(111)가 형성되지 않는 바디(110)의 상단 부위는 식립되었을 때 잇몸과 동일 선상에 위치된다. 이처럼 픽스쳐(100)의 상단이 잇몸과 동일선상 혹은 다소 높게 식립되는 경우 흔히 티슈 레벨(Tissue Level)이라 부르기도 한다.As shown in FIG. 6 , a screw 111 is formed on the outer surface from the lower end of the fixture 100 to a predetermined height, and the screw 111 is implanted in the alveolar bone. The upper portion of the body 110 where the screw 111 is not formed is positioned on the same line as the gum when implanted. As such, when the upper end of the fixture 100 is placed on the same line as the gum or slightly higher, it is often referred to as a tissue level.
한편, 도 15에서처럼 픽스쳐(100)를 치조골에 식립하였을 때 돌출부(120)는 치조골 상단과 잇몸 상단과의 사이 위치에 형성되는 서버머지드(submerged) 형태로 사용될 수 있다. 즉, 서버머지드 형태로 시술되는 경우 픽스쳐(100)의 바디(110) 상단면은 잇몸 아래, 즉 치조골의 상단부와 일치되게 하고 돌출부(120)는 잇몸 공간에 위치되게 하여, 캡형어버트먼트(200)의 일부가 잇몸에 의해 감싸여지는 형태로 시술할 수 있다. 이 경우는 픽스쳐(100)가 잇몸 보다 낮게 위치되어 식립되는데 이를 본 레벨(Bone Level)이라 부르기도 한다.On the other hand, when the fixture 100 is implanted in the alveolar bone as shown in FIG. 15 , the protrusion 120 may be used in a submerged form formed at a position between the upper end of the alveolar bone and the upper end of the gum. That is, when treated in a submerged form, the upper surface of the body 110 of the fixture 100 is placed under the gum, that is, the upper end of the alveolar bone, and the protrusion 120 is located in the gum space, so that the cap type abutment ( 200) can be treated in a form in which a part is covered by the gums. In this case, the fixture 100 is placed lower than the gum and is also referred to as a bone level.
바디(110)의 상단면(112)은 수평면 또는 미세한 경사면을 이룰 수 있으며, 바람직하게 바디(110)의 상단면(112) 중심으로부터 경사진 결합면(121)을 갖는 돌출부(120)가 형성된다. 돌출부(120)는 바디(110) 상단면으로부터 소정각도를 이루면서 상향 돌출되는데, 상협하광 형태로 돌출되며 돌출 높이는 바디(110) 상단면으로부터 2mm 내지 7mm 범위가 적합하며, 돌출부의 직경은 픽스쳐 상단부의 직경을 고려하여 Φ1.5mm 내지 Φ6.0mm 가 적당하고, 돌출부(120)의 결합면(121)의 각도는 1.5도 내외가 적합하다.The upper surface 112 of the body 110 may form a horizontal surface or a fine inclined surface, and preferably a protrusion 120 having a coupling surface 121 inclined from the center of the upper surface 112 of the body 110 is formed. . The protrusion 120 protrudes upward while forming a predetermined angle from the top surface of the body 110, and it protrudes in the form of a downward light, and the protrusion height is suitable in the range of 2 mm to 7 mm from the top surface of the body 110, and the diameter of the protrusion is the upper end of the fixture. In consideration of the diameter, Φ1.5mm to Φ6.0mm is suitable, and the angle of the coupling surface 121 of the protrusion 120 is suitable around 1.5 degrees.
본 발명의 경우 임플란트 시술을 위해 픽스쳐(100)를 먼저 치조골에 식립하여 초기고정이 이루어지도록 하는데, 이 경우 잇몸 위로 노출되는 픽스쳐(100)의 상단 부위인 돌출부(120)의 높이가 기존의 원피스 타입 임플란트에 비해 낮기 때문에 혀나 음식물에 의한 부딪힘이 감소되므로 초기고정에 보다 유리함을 제공하게 된다.In the case of the present invention, the fixture 100 is first placed in the alveolar bone for an implant procedure so that initial fixation is achieved. Since it is lower than the implant, the impact by the tongue or food is reduced, which provides more advantage for initial fixation.
그리고 크라운(300)의 결합을 위한 캡형어버트먼트(200)가 돌출부(120)에 체결되도록 하는데, 본 발명에서는 어떠한 스크류를 사용하지 않고 캡형어버트먼트(200)를 돌출부(120)에 체결되도록 한다.And the cap-type abutment 200 for coupling the crown 300 is fastened to the protrusion 120 . In the present invention, the cap-type abutment 200 is fastened to the protrusion 120 without using any screws. do.
즉, 픽스쳐(100) 상단면으로부터 돌출 형성되는 돌출부(120)에 캡형어버트먼트(200)가 결합될 수 있도록 캡형어버트먼트(200)의 하단면에 픽스쳐(100)에 형성되는 결합면(121)에 대응하는 경사각을 갖는 오목한 결합홈(210)을 두도록 한다. That is, the coupling surface ( 121) to have a concave coupling groove 210 having an inclination angle corresponding to the inclination angle.
도 5와 같이 캡형어버트먼트(200)에 구비되는 결합홈(210)을 픽스쳐(100) 상단에 형성된 돌출부(120)에 올려 상호 자연스럽게 끼워지도록 한 다음 캡형어버트먼트(200)의 상부로부터 수직 하방으로 힘을 작용시켜 가압하게 되면 캡형어버트먼트(200)의 하단 내측면과 돌출부(120) 하단 외측면에서 콜드웰딩(Colding welding) 방식에 의해 캡형어버트먼트(200)가 픽스쳐(100)와 일체로 결합된다.As shown in FIG. 5 , the coupling groove 210 provided in the cap-type abutment 200 is placed on the protrusion 120 formed on the top of the fixture 100 so that they fit naturally into each other, and then vertical from the top of the cap-type abutment 200 . When the pressure is applied by applying a downward force, the cap-type abutment 200 is formed by a cold welding method on the inner surface of the lower end of the cap-shaped abutment 200 and the lower outer surface of the protrusion 120 to the fixture 100. is integrally combined with
여기서, 말하는 콜드웰딩(Colding welding)이란, 냉간압접이라고도 하며 외부로부터 열이나 전류를 가하지 않고 연성 재료의 경계부를 상온에서 강하게 압축하여 접합면을 국부적으로 소성 변형시켜서 결합시키는 방법을 말하며, 본 발명에 따른 하이브리드 임플란트를 구성하는 픽스쳐와 캡형어버트먼트는 기본적으로 티타늄, 티타늄 합금으로 제작하되, 그외 특수 플라스틱, 지르코니아, 특수합금으로 이루어지도록 함으로써 콜드웰딩을 이용하여 매우 효과적으로 양자를 간단하고도 신속하게 결합되게 할 수 있는 것이다.Here, cold welding refers to a method of bonding by locally plastically deforming the joint surface by strongly compressing the boundary of a flexible material at room temperature without applying heat or current from the outside, also called cold welding, and in the present invention The fixtures and cap-type abutments constituting the hybrid implant are basically made of titanium and titanium alloy. it can be made
보다 구체적으로 픽스쳐(100)는 임플란트 시술을 위해 치조골에 먼저 식립되도록 하는데, 이때 픽스쳐(100)의 상단면으로부터 돌출되는 돌출부(120)는 잇몸 보다 높게 돌출되도록 한다. 즉, 돌출부(120)는 잇몸을 기준으로 볼 때 2mm 내지 7mm 정도 높게 돌출된다.More specifically, the fixture 100 is to be placed first in the alveolar bone for the implant procedure, in this case, the protrusion 120 protruding from the top surface of the fixture 100 is to protrude higher than the gum. That is, the protrusion 120 protrudes as high as 2mm to 7mm when viewed from the gum.
그리고 돌출부(120)는 바디(110)의 상단면 외경 보다 작은 외경을 갖도록 하며, 바디(110)의 센터라인과 동축상으로 돌출부(120)가 형성되고, 바디(110)의 상단면은 수평 또는 미세한 경사면을 이루도록 함이 바람직하다.And the protrusion 120 has an outer diameter smaller than the outer diameter of the upper surface of the body 110, the protrusion 120 is formed coaxially with the center line of the body 110, the upper surface of the body 110 is horizontal or It is preferable to form a fine inclined surface.
그리고 돌출부(120)는 바디(110)의 상단면 외경과 동일한 외경으로 시작되어 소정의 경사각을 이루면서 상향될수도 있다.In addition, the protrusion 120 may start with an outer diameter equal to the outer diameter of the upper surface of the body 110 and may rise upward while forming a predetermined inclination angle.
캡형어버트먼트(200)는 픽스쳐(100)의 돌출부(120)에 맞게 다양하게 제공될 수 있으며, 캡형어버트먼트(200)의 전체적인 높이, 직경은 인접치아와의 관계를 고려하여 저작력과 심미성을 향상시킬 수 있도록 한다. 그리고 캡형어버트먼트(200)는 도 4와 같이 기본적으로 대칭적인 구조를 이루도록 한다.The cap-type abutment 200 may be provided in a variety of ways to fit the protrusion 120 of the fixture 100, and the overall height and diameter of the cap-type abutment 200 may have masticatory force and esthetics in consideration of the relationship with adjacent teeth. to be able to improve And the cap-type abutment 200 is basically to form a symmetrical structure as shown in FIG.
이어서 본 발명에 따른 하이브리드 임플란트의 또 다른 실시예들에 대해 설명하도록 한다.Next, another embodiment of the hybrid implant according to the present invention will be described.
도 7의 제2실시예와 같이 캡형어버트먼트(200)의 하단측 외면에는 외측으로 확장되는 플랜지부(220)가 형성될수 있다.As in the second embodiment of FIG. 7 , a flange portion 220 extending outwardly may be formed on the outer surface of the lower end side of the cap-shaped abutment 200 .
도시된 것처럼 캡형어버트먼트(200)의 하단측에 형성되는 플랜지부(220)는 하단 부근에서 외측으로 완만한 경사를 이루면서 형성되어 바디(110) 상단면에 대한 접촉면적을 더욱 넓게 형성시키면서 결합을 이루게 되고, 크라운과의 결합면적을 넓게 형성시킨다.As shown, the flange portion 220 formed on the lower side of the cap-type abutment 200 is formed while forming a gentle inclination to the outside in the vicinity of the lower end of the body 110, while forming a wider contact area for the upper surface of the combined and form a wide bonding area with the crown.
캡형어버트먼트(200)의 하단측 외면에 플랜지부(220)가 형성됨으로써 보다 안정적으로 픽스쳐(100)와 결합이 이루어지며, 크라운(300)이 결합되었을 때 잇몸과의 접촉면에 심미성을 향상시켜줄 수 있고, 이물질 유입의 가능성을 낮출 수 있다.The flange part 220 is formed on the outer surface of the lower side of the cap-type abutment 200 to be more stably coupled with the fixture 100, and when the crown 300 is coupled, it will improve the aesthetics of the contact surface with the gums. and can reduce the possibility of ingress of foreign substances.
즉, 플랜지부(220)의 높이나 형상을 환자의 잇몸 높이에 따라 적합한 것을 선정할 수 있도록 플랜지부(220)의 높이 각도 등은 다양하게 변형 실시될 수 있다.That is, the height and angle of the flange part 220 may be variously modified so that the height or shape of the flange part 220 can be selected according to the height of the patient's gums.
다음으로 제3실시예에 대해 설명하도록 한다.Next, the third embodiment will be described.
도 8과 같이 제3실시예에서는 캡형어버트먼트(200)의 상단측에 지그 연결부(230)가 형성되는 것을 특징으로 하는데, 지그 연결부(230)는 돌출되거나 함몰된 형태일 수 있다.As shown in FIG. 8, in the third embodiment, the jig connection part 230 is formed on the upper side of the cap-shaped abutment 200, and the jig connection part 230 may be in a protruding or recessed form.
캡형어버트먼트(200) 상단에 지그 연결부(230)를 두는 이유는 픽스쳐(100) 식립 후 캡형어버트먼트(200)를 콜드웰딩 방식으로 돌출부(120)에 결합시키게 되고, 이후 크라운(300)을 캡형어버트먼트(200)에 부착함으로써 임플란트 시술이 완료된다.The reason for placing the jig connection part 230 on the top of the cap-type abutment 200 is to couple the cap-type abutment 200 to the protrusion 120 by a cold welding method after the fixture 100 is installed, and then the crown 300 By attaching the to the cap-type abutment 200, the implant operation is completed.

이어서 본 발명의 제8실시예에 대해 설명하도록 한다.Next, an eighth embodiment of the present invention will be described.
제8실시예에서는 도 13과 같이 픽스쳐(100)의 돌출부(120)에 임시로 결합될 수 있는 보호캡(400)이 제공될 수 있는 것을 특징으로 한다. 본 발명의 하이브리드 임플란트는 픽스쳐(100)를 먼저 치조골에 식립하여 소정의 기간 동안 초기 고정이 이루어질 수 있도록 한 다음 캡형어버트먼트(200)를 돌출부(120)에 콜드웰딩 방식으로 결합하게 되는데, 픽스쳐(100)의 초기 고정 시간동안 돌출부(120)는 잇몸 위로 노출된 상태로 있게 된다.In the eighth embodiment, as shown in FIG. 13 , a protective cap 400 that can be temporarily coupled to the protrusion 120 of the fixture 100 may be provided. In the hybrid implant of the present invention, the fixture 100 is first placed in the alveolar bone so that initial fixation can be made for a predetermined period, and then the cap-type abutment 200 is coupled to the protrusion 120 in a cold welding method. During the initial fixing time of (100), the protrusion (120) remains exposed above the gums.
잇몸 위로 노출되는 돌출부(120)는 환자의 혀가 접촉됨에 따라 혀를 다칠 수 있으므로 플라스틱 또는 티타늄 소재의 보호캡(400)을 씌워 혀를 보호하며, 심미성을 고려할 수 있도록 한다.Since the protrusion 120 exposed above the gums may injure the patient's tongue as it comes into contact, a protective cap 400 made of plastic or titanium material is covered to protect the tongue, and esthetics can be considered.
한편, 본 발명의 하이브리드 임플란트는 다음과 같은 장점도 있다.On the other hand, the hybrid implant of the present invention also has the following advantages.
도 14는 본 발명의 하이브리드 임플란트에 있어 캡형어버트먼트의 설치 자유도를 보여주는 것으로서, 픽스쳐 상단의 돌출부는 원형 단면을 이루고 있으므로 캡형어버트먼트를 360°어떤 방향으로도 배치하여 결합시킬 수 있다. 특히, 캡형어버트먼트가 비대칭 구조를 갖는 경우 본 발명의 이러한 특징은 픽스쳐에 캡형어버트먼트를 결합할 때 주위 치아와의 관계상 가장 적합한 방향으로 캡형 어버트먼트를 배치하여 픽스쳐에 결합되게 해야 하는데 본 발명의 나사결합이 아니므로 캡형어버트먼트를 회전시켜가면서 가장 적합한 위치를 선정 후 하방으로 가압하여 간단하게 픽스쳐와 체결되게 할 수 있다.Figure 14 shows the installation freedom of the cap-type abutment in the hybrid implant of the present invention, since the protrusion of the top of the fixture forms a circular cross-section, the cap-type abutment can be arranged and coupled in any direction 360°. In particular, when the cap-type abutment has an asymmetric structure, this feature of the present invention requires that the cap-type abutment be disposed in the most suitable direction in relation to the surrounding teeth to be coupled to the fixture when the cap-type abutment is coupled to the fixture. However, since it is not the screw coupling of the present invention, the most suitable position can be selected while rotating the cap-type abutment and then pressed downward to be easily fastened with the fixture.
또한, 본 발명의 하이브리드 임플란트는 픽스쳐를 치조골에 식립 후 잇몸 위로 노출되는 돌출부를 이용하여 인접치아와의 위치, 높이, 간격 등 PATH를 맞출 때 돌출부를 가이드핀으로 하여 픽스쳐 식립 후 치아간의 간격, 폭 등을 측정하는데 활용할 수 있다는 장점도 있다.In addition, the hybrid implant of the present invention uses the protrusion exposed above the gum after placing the fixture in the alveolar bone to use the protrusion as a guide pin when aligning the PATH with the adjacent teeth, such as the position, height, and spacing with the adjacent teeth. There is also the advantage that it can be used to measure the back.
이상 설명한 바와 같은 본 발명의 하이브리드 임플란트는 픽스쳐와 어버트먼트를 볼트를 이용하지 않고서 간단히 결합할 수 있도록 함으로써 시술이 보다 간편해질 수 있도록 함은 물론이고 임플란트 시술 이후 자주 발생되었던 어버트먼트의 풀림 현상으로 인한 문제점을 해결할 수 있다.As described above, the hybrid implant of the present invention allows the fixture and the abutment to be simply combined without using a bolt, thereby making the procedure simpler and the abutment loosening phenomenon that occurs frequently after the implant procedure. problems can be solved.
본 발명의 하이브리드 임플란트는 원피스 타입과 투피스 타입 임플란트의 단점은 버리고 장점만을 이용하도록 하는 것으로 기존 제품들을 대체하여 치과용 임플란트로 사용될 수 있다.The hybrid implant of the present invention can be used as a dental implant by replacing existing products by discarding the disadvantages of the one-piece type and the two-piece type implant and using only the advantages.
